I am getting “unable to configure SMTP server” while saving the settings.
Below are the links with SMTP configuration steps that will help you understand the fields mentioned in the configuration.
Also, check the connectivity between the DNIF components and the SMTP server.

I’m having the same issue, no matter what I enter in the fields, the error “unable to configure SMTP” is displayed. From the server, I am able to telnet to the SMTP host without issues.
Also; It seems that a “non @ username” is not allowed in the configuration? When using SendGrid, the username is always apiuser, without a trailing suffix. Currently using a other SMTP server to test with, but Sendgrid is preferred for us
